Reply To: noise figure measurement

Hi Andrew,

thanks for the information about the SA44/124.

I played around with the new NF function and compared this with the values I get from an Eaton 2075. I have a HP 346B and a selfmade noise source that are reproducing realistic values. In the frequency range of about 800 to 1000 MHz I am always getting values to high. The rest is really close to what is expected. I will invest some more time next week and have a closer look.

For my last question:
There was a interesting article here

I have not tried this, but the steps to use this measurement method are very close to yours.

Best,

Volker
